Pill use leads women to choose 'wrong' partner

Taking the contraceptive pill can lead a woman to choose the wrong partner, latest research suggests.

The pill is thought to disrupt an instinctive mechanism that brings together people with complementary genes and immune systems.

For the study, UK researchers asked 100 women to indicate their preference on six male body odour samples, drawn from 97 volunteer samples, before and after initiating contraceptive pill use.

Lead researcher Dr Craig Roberts, from the University of Liverpool, said: ‘The results showed that the preferences of women who began using the pill shifted to men with genetically similar odours.’
